Description

Background: I was analysing JIRA issues related to the NIOHub fatal channel termination causing massive disconnection of agents. It appears that the SingleLaneExecutor is not completely correctly used there...

TL;DR: A single packet sent to the channel with pending shutdown may cause the termination of all remoting channels in JNLP1, JNLP2, CLI, and CLI2 protocols. JNLP4 does not seem to be affected.
